"DESCRIPTION"
Header "DESCRIPTION" The functions EVP_PKEY_print_public(), EVP_PKEY_print_private() and
\fBEVP_PKEY_print_params() print out the public, private or parameter components
of key pkey respectively. The key is sent to \s-1BIO\s0 out in human readable
form. The parameter indent indicates how far the printout should be indented.
The pctx parameter allows the print output to be finely tuned by using \s-1ASN1\s0 printing options. If pctx is set to \s-1NULL\s0 then default values will be used.
The functions EVP_PKEY_print_public_fp(), EVP_PKEY_print_private_fp() and \fBEVP_PKEY_print_params_fp() do the same as the \s-1BIO\s0 based functions but use \s-1FILE\s0 fp instead.
"NOTES"
Header "NOTES" Currently no public key algorithms include any options in the pctx parameter.
If the key does not include all the components indicated by the function then only those contained in the key will be printed. For example passing a public key to EVP_PKEY_print_private() will only print the public components.
"RETURN VALUES"
Header "RETURN VALUES" These functions all return 1 for success and 0 or a negative value for failure.
In particular a return value of -2 indicates the operation is not supported by
the public key algorithm.

"HISTORY"
Header "HISTORY" The functions EVP_PKEY_print_public(), EVP_PKEY_print_private(),
and EVP_PKEY_print_params() were added in OpenSSL 1.0.0.
The functions EVP_PKEY_print_public_fp(), EVP_PKEY_print_private_fp(), and EVP_PKEY_print_params_fp() were added in OpenSSL 3.0.
